发明名称 RADIO FREQUENCY TRANSPONDERS HAVING THREE-DIMENSIONAL ANTENNAS
摘要 <p>Three-dimensional objects, such as product packages or gaming tokens, have formed thereon a three-dimensional antenna pattern coupled to a radio frequency transponder, such as an RFID tag. The antenna pattern permits signals from the transponder to be received regardless of the orientation or stacking condition of the objects. In one variation, a gaming token has formed thereon antenna portions on a top, bottom, and sides thereof, and a label having an RFID chip and antenna connectors is applied to the gaming token, thus coupling the RFID chip to the antenna that is formed around the gaming token.</p>
